Different Physiognomies and the Structure of Euglossini bee (Hymenoptera: Apidae) Communities

open access: yesSociobiology, 2018
Our aim was to evaluate the occurrence of orchid bees in remnants of the Atlantic Forest. We sampled specimens from five regions of Southeast Brazil, covering three different physiognomies of the Atlantic Forest (mixed Araucaria forests with high ...

Orchid bees as bio-indicators for organic coffee farms in Costa Rica: Does farm size affect their abundance?

open access: yesRevista de Biología Tropical, 2006
The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs non-organic coffee farms was studied in Atenas and San Isidro, Alajuela, Costa Rica using 1.8-cineole as lure.

Aesthetic values as relational values: Environmental aesthetics in go‐along interviews

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1974-1986, June 2026.
Abstract Aesthetic values are often categorised as a type of relational values, yet their shared characteristics with other relational values remain largely unexplored. To address this gap, we turn to Emily Brady's theory of environmental aesthetics; her interpretation of aesthetic value exhibits important parallels with the concept of relational ...

Evidence of introduced honeybees (Apis mellifera) as pollen wasters in orchid pollination

open access: yesScientific Reports
Biological invasions threaten global biodiversity, altering landscapes, ecosystems, and mutualistic relationships like pollination. Orchids are one of the most threatened plant families, yet the impact of invasive bees on their reproduction remains ...

Are orchid bees at risk? First comparative survey suggests declining populations of forest-dependent species

open access: yesBrazilian Journal of Biology
The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely ‘Reserva Biológica de Sooretama’ (REBIO Sooretama) and ‘Reserva Natural Vale’ (RNV), were surveyed for their orchid-bee faunas.

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3428-3443, June 2026.
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

Are orchid bees useful indicators of the impacts of human disturbance?

open access: yesEcological Indicators, 2019
Biodiversity and ecosystem functions are threatened by human disturbance, and tropical forests are one the most vulnerable habitats. Monitoring the impacts of disturbance and the success of conservation projects is crucial, and to do this effectively it ...

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, Volume 2026, Issue 5, May 2026.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1127-1137, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...
